Dark instincts
(Book)

Whenever wolf shifter Roni Axton is near Marcus Fuller, there's a crackle of sexual awareness that's intoxicating ... and deeply annoying. Marcus is a pack enforcer who oozes power, but Roni is lethal in her own right. His possessive gaze makes one thing clear. Marcus has singled her out for seduction, and he wants to make her sit up and beg. When a brutal attack by a jackal pack forces them to work together, it's the perfect opportunity for Marcus to chip away at her defenses-- until he falls into his own trap, completely unprepared for the intensity of their connection. For Marcus, claiming Roni once will mean needing her forever.
